sampūjya deva-ṛṣi-varyam ṛṣiḥ purāṇo

prāha prabho bhagavate karavāma he kim
sampujya -- fully worshiping; deva -- among the demigods; rishi -- the sage; varyam -- greatest; rishih -- the sage; puranah -- primeval; narayanah -- Lord Narayana; nara-sakhah -- the friend of Nara; vidhina -- by scripture; uditena -- enjoined; vanya -- with speech; abhibhashya -- conversing; mitaya -- measured; amrita -- with nectar; mishtaya -- sweet; tam -- him, Narada; praha -- He addressed; prabho -- O master; bhagavate -- for the lord; karavama -- We may do; he -- O; kim -- what.
In this verse the words narayano nara-sakhah indicate that Krishna is Himself the Supreme Lord, Narayana, who appeared as the friend of the sage Nara. In other words, Lord Krishna is rishih puranah, the original and supreme spiritual master. Nevertheless, following the Vedic injunctions (vidhinoditena) that a kshatriya should worship the brahmanas, Lord Krishna happily worshiped His pure devotee Narada Muni.
